John McCain, Barack Obama Make Final, Frenzied Push to Close 2008 Election

Sen. Barack Obama capped what he called a two-year long "wild ride" by cautioning today that if he becomes president, he won't be able to "get everything done all at once."

Obama talked with ABC News' Ann Compton about the first term of what would be an historic presidency if he defeats Sen. John McCain Tuesday.

The Election eve peek at an Obama administration came as fresh polls indicate Obama is pulling away, while McCain was promising pumped up supporters an Election Day upset.

The latest ABC News/Washington Post poll indicates that Obama has established a 54-43 point lead over his Republican rival on the eve of the vote.

McCain's camp, however, insists that its internal polls show the Republican closing the gap, particularly in battleground states where the election will be decided.

Obama started the day by warning supporters in Jacksonville, Fla., that the election was close, particularly in Florida.

"Don't believe for a second this election is over. ... It's going to be close," Obama said. "Now it's all about who wants it more, who believes it more."

Sometime during his Jacksonville stop, Obama also received the sad news that his beloved grandmother who largely raised him had died.

Obama had suspended his campaign last month so he could travel to Hawaii and see one last time the woman he affectionately called Toot, short for the Hawaiian word tutu for grandparent. The Obama campaign said he would continue with a day packed with campaign events.

Despite his warning about over confidence, Obama was willing to discuss his presidency and how many of his campaign promises he'll be able to keep.

"Well, I think that we are not going to get everything done all at once, because of this financial crisis that's going to require a lot of attention, a lot of resources," Obama told ABC News.

"It means that some priorities may get deferred," he said.

Obama said changing the tax code, investing in clean energy, controlling health care costs and improving the education system remain his "core commitments."

"We will have progress on all fronts by the end of my first term," Obama said.

The Illinois senator looked back at his victory in the Iowa caucuses and his upset loss to Sen. Hillary Clinton in the New Hampshire primary nearly two years ago, to where he is considered the front-runner in Tuesday's election.

"It has been a wild ride," he told Compton.

McCain, however, was undaunted by the polls and promised his supporters a come-from-behind win on Tuesday.

"The pundits may not know it, but the Mac is back," McCain told a cheering crowd in Tampa, Fla., where he kicked off a grueling final seven state sprint. "We're going to win this election."

"We never give up. We never quit. We're going to win," he vowed.

The Arizona senator was in such a buoyant mood that he even joked about his rival's running mate, Sen. Joe Biden, who has repeatedly made statements on which the McCain campaign has pounced.

McCain chuckled as he referred to Biden as "Joe the Biden, the gift that keeps on giving."

Both campaigns launched a frenzied push for votes across 13 states in a single day to encourage their supporters to get out and vote, and to appeal to the handful of voters who have yet to make up their minds.

A number of polls in three critical battleground states, however, that seemed to bolster Obama's historic bid to be the nation's first black president, and McCain's presidential hopes may be in jeopardy.
